Regular exercise is widely recognized as a key factor in maintaining good health and reducing the risk of premature death. While exercise is beneficial for both men and women, recent studies have shown that women may actually experience greater benefits from the same amount of physical activity compared to men. This gender gap in exercise-related health outcomes has important implications for public health and underscores the need for tailored exercise recommendations for men and women.
Exercise has long been associated with numerous health benefits, including improved cardiovascular health, increased muscle strength and endurance, better mental health, and a reduced risk of chronic diseases such as obesity, diabetes, and certain types of cancer. The Department of Health and Human Services recommends that adults engage in at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week, along with muscle-strengthening activities at least twice a week.

Despite the well-known benefits of exercise, studies have consistently shown that women tend to engage in less physical activity than men. Various factors contribute to this disparity, including societal expectations, time constraints, and caregiving responsibilities. However, recent research suggests that even relatively small amounts of exercise can still provide significant benefits for women’s health.
A national study analyzed the exercise habits of over 412,000 men and women and found that men were more likely than women to engage in regular physical activity and strength training exercises. However, the study also revealed that women who exercised regularly experienced a 24% lower risk of premature death compared to women who did not exercise. In contrast, men who exercised regularly had a 15% lower risk of premature death compared to their sedentary counterparts.
One of the most intriguing findings from the study was that women appeared to derive greater benefits from the same amount of exercise compared to men. For example, just 140 minutes of moderate exercise per week reduced women’s risk of premature death by 18%, while men needed 300 minutes of exercise per week to achieve a similar reduction in risk.
The researchers also observed that the reduction in risk increased with the duration of exercise for both men and women, plateauing at around 300 minutes of moderate activity per week. At this level, women had a 24% lower risk of premature death from any cause compared to sedentary women.
The reasons behind the gender gap in exercise benefits are still not fully understood. However, researchers have proposed several hypotheses to explain this phenomenon. One possible explanation is that women may engage in higher relative loads of physical effort during exercise compared to men. Additionally, differences in skeletal muscle properties between men and women could contribute to variations in the response to exercise.
Women tend to have more capillaries in their muscles, allowing for better blood flow and oxygen delivery during exercise. Higher levels of the hormone estrogen in women may also enhance blood flow, further contributing to the observed gender differences in exercise benefits.
The findings from this study have important implications for exercise recommendations and public health initiatives. The current guidelines recommend that both men and women engage in at least 150 minutes of moderate-intensity aerobic activity per week. However, these results suggest that women may achieve similar health benefits with less exercise.

Rather than focusing solely on specific time-based recommendations, exercise guidelines should take into account the individual’s sex and tailor the recommendations accordingly. Women should be encouraged to engage in regular physical activity and strength training exercises, even if they cannot meet the recommended minimum duration. Every bit of progress counts, and women can still reap significant health benefits from incorporating even small amounts of exercise into their daily routines.
Despite the proven benefits of exercise, many women face barriers that prevent them from engaging in regular physical activity. Time constraints, family responsibilities, work obligations, and societal expectations can all make it challenging for women to prioritize exercise. To address these barriers, healthcare professionals, policymakers, and communities need to work together to create supportive environments that make exercise more accessible and enjoyable for women.
Efforts should be made to provide women with resources and information about the benefits of exercise, as well as strategies for incorporating physical activity into their daily lives. This could include promoting active transportation options, such as walking or cycling, providing affordable and convenient fitness facilities, and offering educational programs that address common misconceptions and concerns about exercise.
